Hydrostop 200mm PVC Rearguard Waterstop – CJ928

PVC waterstops have been used for many years and are still considered one of the best forms of waterstop. The PVC extrusion creates a tough, watertight barrier between the concrete joints and prevents the ingress of water through the joint.
Rearguard waterstop needs to be located at the back of the joint and is typically adhered to formwork. A welding iron is required to weld the two ends together should the waterstop need to be joined. Factory-made intersection pieces are also available to make site installation easier.
CJ928 is designed specifically for control joints and should not be used for expansion joints.
